How do I explain it? Armin is one of the 104th cadet cadets, this time he sleeps alone in his room, maybe a dormitory. Armin is 15 years old, in junior high school he often wore a thick blanket and when he had a cold it really showed who he was, he wore a white shirt and black trousers. His hair is blonde and has a bob style, his eyes are big blue, his nose is sharp, his eyebrows have sideburns. Armin is a shy and smart person.
